AVME9675: VME64 Carriers with Geographical Addressing

• Non-intelligent VME64x IP carrier

• Holds four IP modules

• Rear Access I/O

• Supports two interrupt channels per IP

The AVME9670 and AVME9675 are nonintelligent slave boards that interface up to four IP modules to the VMEbus. The only difference is that the AVME9675 adds fully implemented geographical addressing. Both are full-height (6U) IP carrier cards that use VME64-compliant connectors to increase the quantity of rear I/O connections beyond that of standard VME. Although the rear connectors are VME64, the electrical interface is standard VME A24/A16. This means that nearly all CPU products (VME64 or not) can still enjoy full access to the IP modules.

Description

When used with a VME64 backplane, the AVME9670 brings all 200 I/O points out the rear P0 and P2 connectors. This convenience eliminates messy cables from hanging out the front of the cage. In addition to a cleaner cage design, it is also much easier to insert and replace boards into the system.

Acromag’s carrier boards provide full data access to the IP module’s I/O, ID and memory spaces. With full access to the programmable registers, you can easily configure and control the operation of the IP modules from the VMEbus.

Up to two interrupt requests are supported for each IP module. The VMEbus interrupt level is software programmable.

Individual passive filters on each IP module power supply line provide optimum filtering and isolation between the IP modules and the carrier board.
